FDOT Standard Plans Index 450-502: Beveled Bearing Plate Details - Prestressed Florida - U Beams

Design Criteria

Design Criteria AASHTO LRFD Bridge Design Specifications ; Structures Detailing Manual ( SDM ) ; Structures Design Guidelines ( SDG )

Design Assumptions and Limitations

Design Assumptions and Limitations This Index contains generic details and notes for beveled and embedded bearing plates for us e with Prestressed Florida - U Beams. Completion of the "Bearing Plate Data Table" is required. Use this standard with Indexes 45 0 - 210, 45 0 - 248, 45 0 - 254, 45 0 - 263 and 45 0 - 272.

Embedded B earing Plates A and Beveled Bearing Plates B are required for all beams on grades greater than 2%.

Payment

Payment The cost of beveled and embedded bearing plates is incidental to the cost of the prestressed beams they are used with. No separate payment is made.

What your plans must show

Plan Content Requirements for this index — the SPI's checklist for designers.

• - 210, when single pedestals are used beneath the beam ends. For split pedestals beneath double bearings, adjust the upper pedestal elevation to utilize the same thickness bearing plate on the left and right sides of the beam as shown below. Slope and Cross Slope parameters in these equations require decimal units and correct sign convention:
